So you've built a new data product, congratulations! Before you move on to the next challenge, you still have lots of work to do if it's going to have a real impact in your organization. Hopefully your stakeholders have been closely involved in the development process, but even if they have, the rest of the business needs to know about your product and how it can make their lives better. If your target users don't know your product exists then they are never going to use it. If you haven't already got one, you need a marketing plan.
